Significantly superior tool? Now wait a second!
There's a place for both tools for darn sure. The cam lock puller is a great little device... if you made, say, 300 mistakes with rifle rounds, it would come in pretty handy. But there are places where the kinetic puller is much better than the cam-lock, and lead/plated handgun bullets is just one of those examples.
With the kinetic puller, you spend like $15 and you have a kinetic puller. If you don't tap it on concrete but find a wood block instead, the damn thing will last for a helluva long time. I got 15 years out of my last one.
With the cam lock, you need to be at your press or it's worthless. And if you have a die in your press (if you are at the bench there's a good chance you will) then you have to screw out that die. Then you have to screw in the cam-lock puller. Then you have to make sure you have the right caliber collet. If you don't, add it to your shopping cart. All of that to pull one screwed up round.
If you need to pull 20 rounds (or 300!) then it's ideal. If you need to pull 2 or 3, for damn sure, I'm sticking with the kinetic puller.
